Fix showmedium errors and make mla7 work.
With the biblatex-mla package, showmedium can only be set when using mla7. It defaults to true. So the solution to all the errors is to actually enable mla7 when passed the class option and not try to change showmedium when passed the mla8 and mla8alt options.
This fixes the error in issue #5 (closed).
